Detector Electronics Corp. (Det-Tronics) recently announced an NTMOS hydrogen sulfide (H2S) gas sensor that detects low H2S gas concentrations in five seconds or less while tolerating harsh environments that experience extreme temperature and/or humidity conditions. Det-Tronics is part of UTC Fire & Security, a unit of United Technologies Corp. Third-party tested to ISA-92.0.01, the NTMOS H2S gas sensor detects hydrogen sulfide in conditions that harm electrochemical and standard MOS sensors. The sensor is packaged in a rugged housing, protected by a sintered stainless steel flame arrestor, and can be installed in Class I, Division 1 locations. The NTMOS gas sensor can be installed as a stand-alone sensor or combined with a display for local indication.
